An integrated method is proposed for the rapid prediction of the aerodynamic and aeroacoustic performance of single-rotation propellers. This method combines an enhanced lifting-line method with two-dimensional (2D) Reynolds-averaged Navier–Stokes (RANS) simulations to construct the required aerodynamic database, while far-field noise is evaluated using the Ffowcs Williams–Hawkings (FW–H) acoustic analogy. The 2D RANS calculations are performed for blade sections to account for compressibility effects, enabling accurate reconstruction of steady surface pressure distributions and spanwise aerodynamic loading within the lifting-line method. The FW–H formulation is used to predict both thickness and steady loading noise. Validation against a reference propeller demonstrates a good agreement in both aerodynamic and aeroacoustic predictions. The maximum error in thrust coefficient remains below 3% across the full range of advance ratios, while the maximum deviation in sound pressure level is 0.599 dB. In addition, the proposed method reduces computational cost by approximately one order of magnitude compared with full three-dimensional computational fluid dynamics and acoustic simulations, requiring only several central processing unit hours. The proposed method provides an efficient and reliable tool for the design and analysis of high-efficiency, low-noise propellers.
